Terrifying.
The video shot over the weekend shows a man as he walks along a trail.
He suddenly turns after he hears something behind him and is surprised that the cat is literally feet away.
He says “oh, sh*t”, they loudly roars which appears to have scared it off.
The man posted the video on social media, writing “I was stalked by a mountain lion so I ran up on and scared it away with a roar at the last minute.”
